Special Abilities
Magic circle against good(SU)
Magical Strike (EX) Its gore attack is treated as a magic evil weapon for the purposes of damage
reduction.
Wild Empathy(SU)They retain their wild empathy because they are defending nature in their own way.
When a unicorn dies there is a chance it will rise as a vampire to seek it's revenge. It feeds only on humaniods and domestic animals. It cannot turn it's fellow unicorns unless they are already dead. It can turn other sorts of horses, cows, mules, ect. It cannot take back it's original horn, but
it will seek the one who took it. They may serve as mounts for winter druids or Gnoll rangers.

Phantom Hitchhikers are beings that don't know they are dead, and with the strength of that belief they form an illusionary (sp) body that's 75% real. They hitch rides to their destination with cars, trucks, caravans, or whatever.

"See the hitcher with the sad eyes?
Be ready for a bad surprise.
Give a ride or leave them be.
The murderous ambushers you soon will see!"

If near their remains, they act out their death.
If avenged or given a funeral, they transform into a petitioner.

Taunting Fruit.
This orange colored fruit grows on semi tropical trees.
It has eyes and a mouth that is forever taunting everyone.
It is often grown in glass and wood houses which the fruit calls "Not really greenhouses." Note that it has lots of vitamin C and is a sovern cure for scurvy. It is often juiced or made into tarts. Some like to throw them into dungeon rooms to set off traps and ambushes.
Supposedly, they came in a time machine that crashed and noone could repair.
It's a tiny plant monster. It crawls like a worm, and can roll.
Speed 5, Hits 1D2 +jester or bard levels.

Order Loving Geometric Golems
These things that reside in the plane of pure law are made of an unfamiliar alloy. They come in several forms.
Type I Sphere
Type II 4 sided pyramid
Type III Cube
Type IV 8 sided spindle
Type V 10 sider triangle formed
Type VI 12 sided pentigon formed
Type VII 20 sided triangle formed
Type VIII 30 sider (very rare)
Type IX The unique godlike 100 sider.
They all have spirits of purest lawful neutral ancored inside of their hull by a soul symbol. Their eyes(1 per roman numeral) can be closed and their limbs can be retracted (2 arms and 2 legs seemed practicle) allowing them to roll for charges and running speed.
Thus a OLGG Sphere is size M and can slam for 2D6 with at least a 10 start. It might have 4D8 before class levels.

The Were-Cephlapoid
New details.
It has telepahic powers. If it succeds in reading thoughts, charming, or dominating, the target must fort save to avoid contracting the disease. An infected Were Cephlapoid can only read thoughts, and the DC is just 15. A born Were-Cephlapoid would have a DC of 20.
They have a beak instead of a mouth(1-4 damage and it attaches) as well as tenticles(4 for infected, 6 for full born) around the beak that also attach.

Necro Knight
A knight in field plate stands by the door. He moves stiffly as he brings his spear to bear. He speaks in a metallic rasp. "Welcome to your last encounter, as mere humans!" The door opens and 6 more of whatever "He" is march out.

Special abilities
Special berserk: 1% cumulative chance it becomes permanently uncontrolled. It will use the special ritual to make more of its kind from corpses and armor. Anything, magical or otherwise, that involves emotion, will make it uncontrolled, as will electrical attacks.
Crushing Grapple: By crushing the windpipe or other bones of a foe it does double and a half the damage of a slam and crits on 19-20.
Immunity to magic: Any spell that allows spell resistance will have no effect, except electrical and emotion based magic. Electrical hastes the creature for 2D6 rounds while emotion based effects slow it for a like amount of time.
Construction: 50% of a corpse and a suit of armor are combined using wires, chains, gears, and other machinery. A special ritual requiring 5,000 gp. in materials has an effect combining animate dead and animate object. If successful the thing retains all its character levels and all mental abilities not dependent on emotions(no rage). Failure produces a standard creature already berserk. Using my ritual system, the chance of success is knowledge engineering + the heal skill + craft arms and armor. The DC is 30.

Pre-petitioners
and I would also like a separate land of the dead. It’s an overlap of the astral, ethereal, and shadow. Where the Pre-petitioners try to figure out if they will head for the outer planes or fight to the prime and become undead. With them are shadowy versions of all the people, places, and objects they interacted with, causing haunts in the prime material.
Basicly, they are enough like they were, that they might not be aware of their death. Other Pre-petitioners or outer planer creatures, might wake them up and help them adjust.
I'm going to develop the prestige classes here. If someone practices being a poltergeist for 5 levels before his buds can wish him back, he'll have those levels.

Poltergeist
Prestige class. Must be a spirit to start.
Role. They can lift and move objects in both worlds with their mind. The objects must be familiar to the poltergeist, be in a place, or near a person they know.
Alignment: Any
Hit Dice: d6
Class Skills: Bluff(Cha), Fly(Dex), Intimidate(Cha), Knowledge(Arcana)(Int), Knowledge(Planes)(Int), Spellcraft(Int), and Use Magic Device(Cha)
Skill Ranks per level: 3+Int modifier.
Class Features
Weapon and armor proficiency: Must be something they handled extensively while alive. Even if they never used it during life they could make the item dance.
Spells-SA: Same as a sorcerer with telekinesis as their bloodline.
See page 72, Core Rulebook, Table 3-14 Sorcerer, and 3-15: Sorcerer Spells Known. Most of the spells are effective only in the Land of the Dead.
Spirit vision. All prepetitioners can see everything in the area of a haunt as long as they are with the object in the Land of the Dead. Everything else in the living game world will look ghostly.

Reaper
Prestige class. Must be a spirit to start.
Role. They can return to life, but only to collect people who should be dead. 10 kills and they get to bring back one person. It can be themselves, or someone else. Like Specter, from DC comics.
Alignment: Not chaotic, but they may change when the offer is made.
Hit Dice: D8
Level 1: Death Touch(constantly on, Dc 10+Cha bonus + level or hit dice), Patron(Outsider with death portfolio), Astral Cloak, Death Scythe(Cold iron weapon that Death touches on a crit)
Level 2: Extra combat feat. Death Scythe becomes +1 to hit and damage.
Level 3: Extra combat feat. Death Scythe becomes +2 to hit and damage.
Level 4: Extra combat feat. Death Scythe becomes +3 to hit and damage.
Level 5: Extra combat feat. Death Scythe becomes +4 to hit and damage.
Level 6: Extra combat feat. Death Scythe becomes +5 to hit and damage.
Patron: Could be a high level angel of death, Inevitable, or Prince of Hell. If the reaper has any spell caster levels, they can teach them any spells from the necromancy school or domain spells from death, law, or the other alignment axis.
Astral Cloak: It allows the wearer to travel to the game world, persist there, and come back. If they hand it to anyone they snap back to the land of the dead, but anyone who wears it can travel to the Land of the Dead, similarly. Snapping back causes one round stunning like Dimension Door.
When they achieve life, they can still turn into their Reaper form when necessary.

Combat Feat-Rip the soul.
Someone with the ghost touch quality on any kind of weapon can (on a crit)reach into a spirit, grab or spear the divine inspiration, and pull it out. Once it's removed, it goes back to the gods, and the spirit is destroyed. The shreds can become part of an Illip or something, but only a True Res. or the open grave ritual has a chance of bringing the personality back together.
Prereqs. Ghost touch and it only works on an intangible spirit, on a crit. Gassious form is vulnerable too.
Normal. Ghosts keep coming back till their issues are resolved, normally.
